Abstract

A pale ginger cat was treated with clofazimine for feline leprosy. During the course of treatment, photosensitisation by clofazimine led to a dermatological disease resembling actinic dermatitis. The mycobacterial disease was eventually cured with clofazimine and the photosensitisation was managed by regulating sunlight exposure. Upon review of the literature, this appears to be the first documented case of drug-induced photosensitisation in the cat.
